The fundraising event, is one of the largest events for women's cancers in Los Angeles and consists over 30,000 participants supporting the cause in some manner, according to EIF.

"It's really important that people continue to support these 'un-sexy' diseases," Modern Family actress Julie Bowen said. "It's not new. It's not bird flu; it's not SARS, and it still hasn't been cured and it kills millions and millions of women every year."

USA Today reported that Berry celebrated Mother's Day in West Hollywood with her 5-year-old daughter Nahla and fiance Oliver Martinez.

Berry who is reportedly expecting a baby boy said that Nahla had been praying for another sibling.

"Every night we pray to God, and she's so sweet. She says, 'God, please bring me a bunk bed and a baby sister.' And I say, 'I can do one of those things, I know for sure! The other one we have to keep praying on.' What do you say to her when she wants that and can't understand why God's taking so long, you know?" Berry revealed on The Wendy Williams Show. 

On the show, Berry also said that she was grateful that she got pregnant at more older age.

"I'm a much better mother at 46, or 41 when I had her, than if I were 21 or 25. I was just a little baby, just trying to figure it out, trying to figure out who I was," she said.
